GCC 4.9 vs. 5.3 vs. 6.0 Compiler Benchmarks On Debian 8.4

With GCC 6.1 due out soon with its plethora of new features and improvements, I decided to run some fresh benchmarks this week of GCC 4.9.3 vs. GCC 5.3 vs. GCC 6.0.0 on a Debian stable system.

From the Xeon E3-1280 v5 system with MSI C236A Workstation, I was using Debian 8.4 x86_64 as the base Linux OS for this benchmarking while building clean compilers of GCC 4.9.3, GCC 5.3.0, and GCC 6.0.0 20160410.

Then a range of C and C++ benchmarks were carried out...

There are some small changes in performance for this Skylake Xeon system, but nothing too major. However, some tests (namely Bullet) failed to build with GCC6.

Many small changes in performance.
